This paper presents a narrative inquiry study on agency development in student-teachers of an English language teacher program at a public university in the south of Colombia. Our goal was to understand how student-teachers develop agency when narratively inquiring their community by planning and conducting community-based pedagogy projects on issues they found pertinent to investigate. The data were gathered through semi-structured focus group interviews, individual journal entries, and video-recorded talks about their inquiries. As a conclusion, we acknowledge that certain social and narrative practices such as interacting within their inquiry groups, interacting with their communities, voicing their communities' necessities, and acting upon the inquired necessities facilitated developing agency and contributed to rethinking their roles as transformative members of their communities.
